ABSTRACT:
A drive mechanism is redundantly equipped with two electric motors so that the second motor can take over the drive function if the first motor should fail, for example for moving equipment in or on a spacecraft. Both electric motors are connected to a common drive shaft. A coupling device makes sure that the defective motor is decoupled from the drive train.
